Abstract: A Field experiment was carried out to study differences between 8 corn(Zea mays) cultivars in accumulation and translocation of heavy metals,for screening out corn cultivars that are low in heavy metal accumulation and suitable to grow in winter in Guangdong Province.Results show that significant differences were found between the cultivars in heavy metal(Cd,Pb,Zn and Cu) concentrations in corn grain and stem and leaves.Cluster analysis of the heavy metal(Cd,Pb,Zn,Cu) concentrations in grain shows that the 8 cultivars could be sorted into three groups.Lingdan-20,Zhengdan958 and Gaoyou-1 were in the group of low-accumulation cultivars.Liyu-6,Fengtian-1,Chaotian-38 and Huabao-1 were in the group of midium-accumulation cultivars.And Yuenuo-1 was a high-accumulation cultivar.Considering furthermore the yield of grains and transference coefficient of heavy metals,Lingdan-20 and Zhengdan-958 were the low-heavy-metalaccumulation corn cultivars suitable to be planted during the winter season in Guangdong Province of China.

Key words: low-accumulation corn, heavy metal, transference coefficient, variety difference
